Pyrethroid-resistant onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), infesting persimmon fruit
A total of 53 strains of onion thrips, Thrips tabaci Lindeman, were established, of which 14 strains were collected from persimmon fruit and 39 strains from a vetch weed, Vicia angustifolia, in commercial persimmon orchards in Wakayama Prefecture. Susceptibility to insecticides was evaluated by the Petri dish-spraying tower method. Pyrethroid-resistant strains and pyrethroid-susceptible strains...

The biocontrol potential of entomopathogenic nematodes (EPNs) against soil-dwelling life stages of the onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae) was evaluated under laboratory and semi-field conditions. The pathogenicity of native isolate of Steinernema feltiae (T1) and three commercial strains, S. feltiae, S. carpocapsae (Rhabditida: Steinernematidae) and Heterorhabditis b...

متن کاملIsolation of Microsatellite Loci from the Onion Thrips, Thrips tabaci
Thrips tabaci Lindeman (Thysanoptera: Thripidae), a cosmopolitan pest insect, is subdivided into at least three genetic lineages that have different biological characters, such as reproductive mode and resistibility to insecticides. Since the lineages are discriminated only by mitochondrial DNA, there is a possibility of gene flow among lineages at the genomic level. Nine polymorphic microsatel...
